AND. WORKING CONDITIONS
Optimum ambient temperature range from -10 ° C to 40 ° C.
Avoid welding in conditions of sunlight and the rain, do not allow the water to penetrate into the interior of the device.
Avoid working in the environment of flammable gas, dust and aggressive. Avoid strong winds, which can cause loss of
protection gas.
B. WORK SAFETY
B. WORK SAFETY
Actually the installed device with overvoltage protection, overcurrent protection and overtemperature switches off
automatically under the conditions beyond the defined as the standard. However, long-term use (eg. Surges) can
cause damage to the welder. Therefore, you should follow the instructions listed below:
C. PRECAUTIONS:
C. PRECAUTIONS:
•
Provide good ventilation
Welding is a device through which a large current is flowing, and the natural ventilation does not provide the
necessary cooling. Therefore, to maintain stability, welder equipped with an internal cooling system. The operator
should check if the vent is not blocked. The distance between the welder and the welded object should not be less
than
0,3m. The operator should always pay attention to ventilation devices, since they depend on it not only achieved
welding quality and performance, but also the life of the device.
•
Avoiding overload
The operators should follow (load designated as the maximum permissible load for a given current) or the welding
current exceeds the maximum permissible electric current to the load. Electrical overload can significantly shorten the
life of welders, and even lead to the burning of its elements.
•
Preventing surges
Keep values in the line supply voltage in the Table "Technical specifications". In normal operation, the automatic
alignment circuit voltage ensures the maintenance of tension in the acceptable range. The supply voltage higher than
the permissible value can damage the welding machine. Operators should be fully aware of this risk and be able to
take appropriate steps.
If a standard load is exceeded, the welder can enter a protective mode and suddenly stop working. This means that
the standard load is exceeded, the heat has launched a thermal switch, which caused the machine to stop. Lamp
lights up on the operating panel welding machine. In such a situation, do not remove the power plug to allow
